• Only use the components and spare parts that we recommend. Always use matching, original Graupner plug-in connections of the same design and material. • Make sure that all of the plug-in connections are tight. When dis- connecting the plug-in connections, do not pull the cables.
Installation The receiver must be mounted on the receiver platform so that its axes are aligned parallel to the model axes and that they remain per- manent. The optional double adhesive pads S8376 are suitable for attaching the receiver. Also suitable are power strips or so-called mirror adhe- sive tape.
The polarity of the plug-in system cannot be reversed. Do not apply force, but insert the plugs to the stop as far as they will go. Note For the receivers Falcon 12 and 12 plus, insert the plugs with the brown or black cable upwards, until the stop. Power supply For the battery connection are designated the ports provided with an additional "B".
1. Prepare the transmitter or model memory to be bound accord- ing to the instructions for binding. 2. Switch the receiver power supply on. 3. The LED of the receiver Falcon 12 (plus) HoTT lights up con- stantly red. 4. Approximately 15 seconds after the receiver is switched on, its red LED starts to flash, indicating that the receiver is now in bind mode.
Receiver GR-18 HoTT and GR-24 PRO HoTT Binding step-by-step 1. Prepare the transmitter to be bound according to its instructions for binding. 2. Switch the receiver power supply on. The LED of a receiver GR-18 HoTT or GR-24 PRO HoTT lights up constantly red.
Gyro initialization before starting the flight operation Each time the receiver system is switched on, the gyro system and possibly also the vario of the receiver require approx. 2 seconds for initialization. During this period, the model must not be moved. Initialization of the gyro step-by-step 1.
RX DATA These instructions also provide information on how to access this ALARM SETTING menu. Change accordingly to the first setting page of the Falcon 12 (plus), GR-18 or GR-24 PRO HoTT receiver. Note The setting values shown in the following display illustrations always show the standard values.

The receiver-specific connection is suitable for connecting telem- etry sensors. When the receiver is switched on, previously con- nected devices are automatically detected. • VOLTAGE After switching through this connection port as described before, a DC voltage of max. 25,5 V can be displayed instead of the receiver voltage.

Digital servos can be operated at a higher frequency. This allows the model to be controlled more quickly. • The operation of higher frequency servos is at your own risk. • For Graupner servos of type "HBS" we recommend a setting of 200 Hz.

You must locate this value in the servo manual and set it correctly. If a value has not been specified, it is probably a standard servo set at 1.5 ms. For Graupner servos of type DES, HVS or HBS, this value is partially programmable. However, we recom- mend sticking with the default setting.

Checking nick Tilt the helicopter so that its nose is facing downwards; the swash- plate moves consequently backwards. Incorrect! Right! Checking roll Tilt the helicopter to the right; the swashplate moves consequently to the left. Checking the tail direction of operation The effect depends on whether the helicopter is equipped with a left- or right-handed rotor and on the mounting side and the direc- tion of rotation of the tail rotor.
